Other objects may be inferred. V be severed exactly at theircenters. Also, that A specific example 'of the invention isillusalthough the stranded element has been detrated by the accompanyingdrawing, Figure 1 scribed as consisting of wires laid together, the

invention is equally applicable to elements made of parallel wires or,in fact, elements made of plural strands arranged together in any formand made of practically any material.

We claim:

1. A method of separating a strand of wires into shorter lengths,including die casting metal about said strand at spaced positionsdefining the shorter lengths and subsequently severing said metal andsaid strand to produce the shorter lengths in the form of units havingdie cast end fittings. I

2. A method,of separating a strand of wires severed into lengths andFigure 2 showing one of the resulting lengths.

More specifically, the numeral 4 indicates a continuous strandedelement, it being undercharacter provided it is made up of a pluralityof wires which are laid together.

The first step is illustrated by Figure 1, sleeves 2 being die castabout the element I at points which are spaced so that the mid-sectionsof these sleeves define the lengths desired. Die casting is construed asmeaning the casting of molten metal into dies which are arranged toencompass the strand I, theresult being that the metal of the sleeves 2engages not only the surface of the element, but also the surfaces ofthe individual wires of which the. element is made, and is down in theinterstices between the latter. The next step is to sever the element atthe about said strand at spaced positions defining the shorter lengthsand subsequently severing said metal andsaid strand to produce theshorter lengths in the form of units having die east end fittings, saiddie casting being conducted by means of dies encompassing said strand sothat said of the wires forming said strand and penetrating into theinterstices between said wires.

wheels 3. The result is a series of lengths which are each of thecharacter illustrated by Figure 2. Each of the lengths carries a half ofone of the die cast sleeves on each of its ends, and unravel.-

into shorter lengths, including die casting metal,

metal is formed as sleeves engaging the surfaces
